Well I'm not sure that the 60mm could not be replaced by another system in the sections.
Something like the Milkor 6 barrel Grenade Launcher or the RVN era China Lake launcher, but using a medium velocity system.
KAC build a High Vel LW system that was man fireable for a program several years back - however its scarier than freefalling in pitch black with no altimeter or AAD...
However until the good idea fairy comes around sprinkling R&D pixie dust - the only system to offer that is the 60mm.
I do like direct precision fire - as I've seen and employed it to great effect (even though Infanteer feels its useless
)
Quite frankly I've seen the 60mm round land near (inside 5m) someone in Iraq and the guy walked away with nary a scratch (there was a tape and BigRed if he's still around here can verify). So I dont think its the end all be all -- frankly I dont think anything short of a nuclear strike is a guarantee --
I'm also less than jazzed about automatic weapons that many, as folks way to often go cyclic beyond their ability to get effective results - and while they are nice and noisy and give everyone a warm fuzzy that lead is going 'that a way'. Perhaps because the majority of my time in Iraq and Afghan was small team work - that did not have the option of using a hammer, I feel that many folks who where not so constrained dont understand how effective it can be.
Secondly I think the Canadian Forces recent love affair with firepower is going the wrong way, at least in the manner that they are viewing the section/squad organic capabilities.
I think IF the CF had been in a much more urban environment with ROE limited employment of CAS and other supporting fires, that the Lessons Learned would be polar opposites to the lessons folks have gained.
Despite all the efforts of the US Army and USMC to bring firepower to bear in Anbar province during the initial Sunni revolt, the majority of the effective work was done by small SOF elements and Marine Reconnaisance delivery close range (and mid range) small arms fires.
Dont get me wrong - I'll JDAM a house in a heartbeat if it guarantees no one needs to risk themselves to kill the occupants - but I also understand that the hammer only works on nails, and hammering a screw when it called for a screwdrive is counterproductive and usually ruins the screw and the material you where trying to screw.
